Please solve for x.
4^3x+1 = 4^5
Answer: x= 1023 /64
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
64x+1=1024
Step 2: Subtract 1 from both sides.
64x+1−1=1024−1
64x=1023
Step 3: Divide both sides by 64.
64x /64 = 1023 /64
x= 1023 /64
Answer:
1023/64
Step-by-step explanation:
4^3x+1=4^5
64x+1=4^5
64x+1-1=1024-1
64x=1023
64x/64}=1023/64
1023/64
1) Simplify the following:
9r + 8 - 4r - 6
2) Simplify the following:
2(x + 3y)
(I know you can’t add some of them because of their variables, but I want the simplified version)
Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem
17. Find the value of x. Round to the nearest degree. (2 points)
Answer:
x = 51°Step-by-step explanation:
Use sine:Sine = opposite __________ hypotenuse We have:Opposite = 7Hypotenuse = 9 Substitute: Sin x° = 7 ___ 9 Sin x° = 0.777....Sin x = 0.7778 = x = 51°Which set of measurements could not represent the side lengths of a right triangle?
A 16 ft, 30 ft, 34 ft
B 9 ft, 12 ft, 15 ft
C 7ft, 24 ft, 25 Ft
D 5ft. 7 ft, 12 ft
The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.
What is a right triangle?The right is a triangle with has one angle 90° and square of hypotenuse is equal to the sum of square of other two legs.
Given that, the set of measurements representing the side lengths of a right triangle,
We will check the measurements by seeing if they are following the Pythagoras theorem or not,
Option A)
16 ft, 30 ft, 34
16²+30² = 1156 = 34²
∴ 16²+30² = 34²
Option B)
9²+12² = 225 = 15²
9²+12² = 15²
Option C)
7²+24² = 625 = 25²
7²+24² = 25²
Option D)
5²+7² = 74 ≠ 12²
Since, 5ft. 7 ft, 12 ft set of measurements are not following the Pythagoras theorem.
Therefore, it's not a right triangle.
Hence, The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.

A standard bathtub holds 70 gallons of water. On average, it takes 7 and 1/2 minutes to drain a bathtub. How many gallons of water go down the drain each minute?
Answer:
9[tex]\frac{1}{3}[/tex] gallons of water
Step-by-step explanation:
To find how many gallons of water go down each minute, divide the total number of gallons of water by the number of minutes it takes to drain:
70/7.5
= 9[tex]\frac{1}{3}[/tex]
So, 9[tex]\frac{1}{3}[/tex] gallons of water go down the drain each minute

14. A veterinarian tells Max that his cat
should lose no more than 30 ounces. The
veterinarian suggests that the cat should
0 to
lose 7 ounces or less per week. What is the
shortest time in weeks and days it would
take Max's cat to lose the 30 ounces?
Answer:
4 weeks 2 days
Answer:
4 weeks 2 days
Step-by-step explanation:
First do 30 divided by 7 to get the number of weeks.
Which is 4 weeks with a remainder of 2.
7 ounces per week is 1 ounce per day.
So to get 2 more ounces that would be 2 days.
Therefore the answer is 4 weeks and 2 days.

How do I solve 3(x−9)=30
Answer:
x = 19
Step-by-step explanation:
use the distributive property
3(x - 9) = 30
3x - 27 = 30
+27 +27
3x = 57
divide by 3
x = 19
Hope this helped! Have a nice day! Plz mark as brainliest!!! :D
-XxDeathshotxX
Answer:
The value of x is 19.
Step-by-step explanation:
The steps are :
3(x- 9) = 30
3(x - 9) ÷ 3 = 30 ÷ 3 [eliminate 3 on left side]
x - 9 = 10
x - 9 + 9 = 10 + 9 [eliminate -9 on left side]
x = 19

Determine the center and radius of the following circle equation: x² + y2 + 2x – 2y – 62 = 0
Step-by-step explanation:
x²+2x+y²-2y=62
using completing the square
x²+2x+1+y²-2y+1=62+1+1
(x+1)²+(y-1)²=64
(x+1)²+(y-1)²=8²
(x-a)²+(y-b)²=r²
by comparison
(a,b)=(-1,1)
a,b is the center of the circle
r=8unit
r is the radius
The scale factor of the scale drawing of a mirror to the actual mirror is represented by the ratio 1 : 8 . If the dimensions of the scale drawing are 3 inches wide by 8.5 inches long, what is the actual area of the mirror?
Answer: 204 square inches
Step-by-step explanation: I’m not really sure, but if you follow through with the normal area identifying method; Length x Width, you should come up with 25.5. After doing this, you could multiply your product by 8 because your actual mirror size is 8 times greater. You will come up with 204 square inches, which would be your final solution. (Once again, I am not sure, just doing how I’ve been understanding from studies).

Consider the following pattern:
87; 84; 81 ...
1.1.1 Find an expression for the nth term of the
sequence
(3)
Answer:
The nth term of the arithmetic sequence is;
90 - 3n
Step-by-step explanation:
Here, we want to find an expression for the nth term of the sequence
Mathematically, let us determine the type of sequence
As we can see;
84 - 87 = 81-84 = -3
The difference between the terms is a constant; this means that the sequence is arithmetic
The nth term of an arithmetic sequence can be represented by;
Tn = a + (n-1)d
in this case, a is the first term of the sequence = 87
d is the common difference of the sequence = -3
The nth term is thus;
Tn = 87 + (n-1)-3
Tn = 87 - 3n + 3
Tn = 87 + 3 - 3n
Tn = 90 - 3n
